On a long road ride when the light intensity is constantly changing, having a collection of Flak Jacket XLJ Replacement Lenses options at your hip optimizes your depth perception. In a jiff you can switch out your standard Flak Jacket XLJ Replacement Lenses for a clear or yellow in more challenging light, or insert a mirrored Iridium® in black or ice for higher intensity conditions. Whatever the circumstance, the lighter or darker Plutonite®, replacement lens blocks 100% UVA, UVB and UVC rays, and meets the ANSI Z87.1 standards for high mass and velocity impact resistance. High Definition Optics® (HDO®) maximizes clarity with a geometry that maintains razor-sharp vision at every turn. A Hydrophobic™ lens coating creates a smudge-resistant barrier that repels water, skin oils and dust to maintain clarity (it is not a permanent coating but can be reapplied as needed with a pen that Oakley includes).
